Since you've obviously seen these posts, these are all good references. Once you've got your cube up and running, you'll need a front end. Excel can be used in a pinch (for internal projects). MSRS is good for operational style reports, but will take some time to fully utilize the tool. Take a look at Performance point for a rapid startup. There's also lots of third party tools and components (i.e. Cognos, Dundas, various Excel add-ins, etc.) that can be used.

Note: a general suggestion to everyone attempting to start a new BI project. While it's great to see the uptake on this technology in the last few years, you'll save considerable time and money by bringing in some outside guidance to get started. This can range from onsight consulting to part-time "mentoring". Now you might have had to "sell in" the whole concept to management, but if you really want to impress them with your business savey, sell in the idea of getting some qualified help to kick start the process. Find someone who can layout a short term schedule, complete with an exit plan and criteria.

Cheers.
